Abstract
A fabrication method and a fabrication device capable of fabricating medium-scale mass production parts. The method of fabricating a composite material hollow part includes: holding a tool on a frame using a holding section that maintains a gap between the tool and the frame, placing a prepreg on the tool, covering the tool and the prepreg using a highly stretchable sheet, securing the highly stretchable sheet and the frame with a securing jig so that tension is applied to the highly stretchable sheet from the top portion of the prepreg where the highly stretchable sheet contacts the prepreg at the highly stretchable sheet and the outer periphery of both the tool and the prepreg to the edges of the highly stretchable sheet, thereby forming an enclosed space that houses the tool and the prepreg, and subsequently evacuating the inside of the enclosed space to wrap the prepreg around the tool.
